Popup Calculator in Windows Forms Calculator

The PopupCalculator class can be used to display a popup Calculator control. This class can be created programmatically.

The PopupCalculator control lets you embed a Calculator control object to a button for example. Drop the button onto the form and add the following code snippet.

c#

private Syncfusion.Windows.Forms.Tools.PopupCalculator popupCalculator1;



private void buttonAdv1_Click(object sender, EventArgs e)

{

    // Create the Popup Calculator.

    popupCalculator1 = new Syncfusion.Windows.Forms.Tools.PopupCalculator();



    // The control that will act as the Popup's parent.

    this.popupCalculator1.ParentControl = this.button1;



    // Set the alignment.

    this.popupCalculator1.PopupCalculatorAlignment = Syncfusion.Windows.Forms.Tools.CalculatorPopupAlignment.Right;



    // Display the Calculator control.

    this.popupCalculator1.DisplayCalculator(Point.Empty);



    //Sets the size of the calculator

    this.popupCalculator1.Size = this.calculatorControl1.Size;

}

vbnet

Private popupCalculator1 As Syncfusion.Windows.Forms.Tools.PopupCalculator
